Option B

An important factor in Oswald Avery's ability  to identify the "transforming principle” as  DNA was the fact that proteins contain very little phosphorus

<h3><u>Explanation:</u></h3>

Oswald Avery manifested an approach to clarify this transforming principle. He then conveyed a range of chemical tests to discover out what it was. Scientists did comprehend that genes were placed on chromosomes and that chromosomes consisted of DNA and proteins.

At the event, yet, proteins resembled to be a better alternative for the genetic material. Chemical analysis explicates that the proportions of elements in the decoction exactly resembled those observed in DNA. Proteins comprise substantially no phosphorus.

Anatomy and
Masja [62]

Answer:

lateral; inferior

Explanation:

In anatomical terms:

  • Superior is towards the head, and <u>inferior </u>is towards the feet.
  • Medial is towards the centre of the body (belly button) whereas <u>lateral </u>is towards the outside of the body (towards the hip bones and arms, for example)
  • Posterior is towards the back (spine), whereas anterior is towards the front (belly)

Therefore, the fingers are lateral (to the side) and inferior (lower) than the heart

At the molecular level, gene duplication often produces novelty in a lineage. This process provides another evolutionary pathway
alukav5142 [94]

Answer:

Bridgham et al. (2006) showed that the interaction between a steroid hormone (aldosterone-M) and its receptor (mineralocorticoid) evolved by Darwinian gradualism. In this work, the authors demonstrated  a primitive affinity between the hormone and its receptor that was initially present in chemically similar but more ancient ligands. This result has implications in understanding the association between gene duplication and the evolution of hormone signaling pathways. For example, in invertebrates, this work reinforces the importance of gene duplication in the existing interaction between paralogous glucocorticoid receptors and their receptor mineralocorticoid genes that were derived from duplication (Thornton 2001).

The publications above cited are the following:
